View Full Version : P0445 EVAP control valve shorted
My only code getting ready for first inspection. Any hints on clearing it would be appreciated. JDM ECU and JCM motor with iWire harness.
I heard back from Brian at iWire. He said that the table I’m using just needs to be modified. Now I have a new question. Anybody know what I can read to educate myself about how to do a nonCobb hookup to my computer?

I think you’d need something like a Tactrix.
I have the tactrix and I have ignorance.

In a nutshell:
1. Download ECUflash: this is free software that uses the tactrix cable to read and write the ECU rom, it can also edit the rom and disable your CEL code.
2. Put the car into reflash mode by connecting the small green "test mode" connector. I've wired in a switch so I just flip the switch to close the connection.
3. Hook up the tactrix cable, open ECUflash and read the rom off of your ECU: the software will ask you to turn the ignition on to power up the ECU. As soon as you turn the key and it sees that the ECU is on, it'll ask if you want to begin reading the rom. The trick here is you have to turn the key and immediately click to start reading within 2-3 seconds. If you take too long, the ECU will go into diagnostic mode and start running the fans. If you don't get it the first time, turn the ignition off and try again.
4. Once you've read the rom onto your laptop, you can begin editing it. Disable which ever check engine codes you'd like. To edit a value in ECUFlash, use increment/decrement keys []. Save the rom and write it back on to the ECU.
5. Unplug the test mode connector when done.
I'm going off of memory so hope I got it all right
